SPECIFICATION forming part of Letters Patent No, 534,557, dated February 19, 1895. pplieation tiled October 11, 189;. Serial No- 525,611. ;(No specimens) To .aZZ whom it may concern.-

Be it known that I, CHARLES GERHARD, a citizen of the United States, residing at J ersey City, in the'countyof Hudson and State of New Jersey, have invented new and useful Improvements in Pyrotechnic Compounds, of'

which the following is a specification.-

This invention relates to a composition of matter to be used for the manufacture of fire take one pint of alcohol and dissolve oneha-lf' a pound of camphor therein, then add one pound of lampuluck, constantly stirring or mixing. Then I add the solution ofadhesiye and mix into these ingredients the remaining ingredients The adhesive iscomposed of three parts of gum tregncanth and two parts of glue which when dissolved in Water and heated ugtil the resulting mass is of a pasty consistence will form an adhesive of great el'iiciencyand readily soluble or capable ofdilution by Water.

The mixture should have a pasty oonsist-. envy, so as to be readily adhe ent. and should will properly dilute the same. Into this inix-.

ture or pasty mass I dip splints or-stalks of woodor other material so that the mass adheres to the stalks, and I then allow the mass to become thoroughly dry,and the stalks can then beheld by their'undipped'portion and the adhering mass ignited.

When burning the mass gives otf a bright light emitting sparks or stars.

' WhatI claim as-'new,.a,nd desire to secure by Letters Patenh'isl. The herein described coinpositionofmatter to be used for pyrotechnicpurposes, consistingof magnesium, starch, larnpblack, iron, camphor-and-gum' tragamnth and glue sub stantially in the PIOPOTtLUH specified.

2. The ,herein'described method of manufacturing a pyrotechnic compound, which methodconsists in dissolving camphor in alcohol, mixing lampbiack therewith, adding gum tragecanth and glue to the mixture, and mixing into these ingredients. magnesium,

starch and iron substantially es set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
